Why is a greenhouse an imperfect analogy for how the Earth's atmosphere behaves?
A)A greenhouse allows longwave radiation to escape and mix with the surrounding air,unlike the Earth's atmosphere.
B)The glass of a greenhouse is designed to allow transmission of both longwave and shortwave radiation,whereas certain atmospheric constituents only allow transmission of shortwave radiation.
C)It is exceedingly rare for a greenhouse to contain carbon dioxide like the Earth's atmosphere contains.
D)Passage of longwave radiation to space is delayed by certain atmospheric constituents,but not trapped like an actual greenhouse.
E)A greenhouse is designed to artificially warm an area and has built in ventilation,whereas there is no such ventilation system in the Earth-atmosphere system.
